PULSE OXIMETER
GENERAL DESCRIPTION

PRODUCT SPECIFICATIONS
OPERATION INSTRUCTIONS
The measurement of oxygen saturation of arterial blood (also known as pulse
oxygen saturation, usually shortened as SpO�) adopts the principles of light
spectra and volume tracing. The LED emits lights with two specific wavelengths,
which are selectively absorbed by oxygenated hemoglobin and
deoxyhemoglobin. The optical receptor measures the changes in the light
intensity after the light passes the capillary network and estimates the ratio of
oxygenated hemoglobin and the total hemoglobin.
SpO�% =
x 100%

■
Explosion hazard. Do not use the oximeter in the presence of flammable
anesthetics mixture with air, oxygen, or hydrogen.
■
When the oximeter is in use, there should not be any great power appliances
as high voltage cables, X-ray machine, ultrasound equipment and electrizer in
use nearby.
■
Keep the oximeter away from dust, vibration, corrosive substances, explosive
materials, high temperature and moisture.
■
This oximeter does not have alarm function; please do not use this product in
the environment where alarm is required.
■
The oximeter should be handled with care so as to avoid shocks and falls.
■
When the oximeter is in use, it must be ensured the batteries have sufficient
capacity; otherwise there might be such phenomena as hstarting-up
abnormalities or inaccurate measurement data, etc.
■
Please do not use such pointed objects as pen point or nails for pressing
operation, otherwise it might cause permanent damage to the surface of the
keyboard.
■
Do not make any clinical judgments based solely on the oximeter. The
oximeter is intended only as an adjunct in patient assessment. It must be used
in conjunction with clinical signs and symptoms, as well as doctor’s diagnoses.
■
To ensure accurate performance and prevent device failure, do not expose the
oximeter to extreme moisture, such as direct exposure to rain. Such exposure
may cause inaccurate performance or device failure.
■
Do not conduct SpO� measurement on the finger smeared with nail polish,
otherwise this will lead to unreliable measurement results.
■
Please do not open the enclosure. The enclosure shall only be opened by the
authorized person.
■
In order to have more accurate measurements of SpO� and PR, the oximeter
should be used in quiet and comfortable environment.
■
Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.
■
Prolonged continuous monitoring may increase the risk of unexpected
changes in skin characteristics, such as irritation, reddening, blistering or
burns. Inspect the sensor site every two hours and move the sensor if the skin
quality changes.
■
Pulse oximeter simulator can not be used to access the accuracy of the pulse
oximeter.
■
The expected service life of the device is three years.
The Fingertip Pulse Oximeter is intended to measure functional arterial oxygen
saturation (SpO�) and pulse rate of adult, pediatric and adolescent patients in
hospital, hospital type facilities, and in the home care envirorment.
The oximeter is not suitable to monitor patients continuously for long term.
LANYARD INSTALLATIONS
BATTERY INSTALLATIONS
NOTES: Be sure to install batteries as
directed by the polarity indicators in the
battery cabin. Batteries in this device are
different than conventional battery
installation.
■
Please put or remove batteries in right
order, or it is likely to damage the device
bracket.
■
Battery polarities must be correctly
installed. Otherwise, damage might be
caused to the device.
1. Press the button down on the back panel of the oximeter.
2 Push the battery cover horizontally along the arrow shown on the back panel
of the oximeter.
3. Install two AAA batteries into the battery cabin.
4. Close the battery cover.
MAINTENANCE
1. Use a soft cloth dampened with either a commercial, nonabrasive cleaner, or a
solution of 70% alcohol in water, lightly wipe the surfaces of the oximeter.
2. Avoid using alcohol-based, amido or acetone-based detergents.
3. The casing of the oximeter should be kept from the contamination of filth and
dirt, and it can be wiped with non-velvet soft cloth. When cleaning, do not
spill the liquid onto the instrument. Ensure no liquid is allowed to enter the
inside of the oximeter.
4. It is forbidden to use such grinding materials as wire brush or metal polishing
agent, because these materials may cause damage to the panels of the
oximeter.
5. Please do not soak the oximeter in liquid.
6. Under normal circumstances, it is unnecessary for the oximeter to have
special maintenance, and cautions must be exercised on the following points
during the use of the oximeter:
■
Please use the oximeter in the environment according to the requirements of
the performance criteria.
■
Avoid exposure or direct sunlight.
■
Avoid excessive radioactive infrared rays or ultraviolet rays.
■
Avoid contacts with organic solutions, dusts or corrosive gases.

The oximeter uses two 1.5 V AAA type batteries and a set of new batteries can be
used for more than 18 hours, depending on concrete battery types.
1. Install batteries as indicated by the battery
installation instructions.
2. Open the oximeter. Insert one finger into the
rubber hole of the oximeter before releasing.
Your nail surface must be upward.
3. Press the function button once on the front panel.
4. Read corresponding data on the display screen.
5. After turning on the oximeter, each time you press the power switch, the
display screen will change to another direction. If you hold down the power
switch, you can adjust the brightness of the screen from 1 to 5.
1. Attach the lanyard through the hole in the middle of the front face as the
arrows show.
2. Complete.
The mechanical activity of the heart causes arterial pulse, by measuring the
pulse we can get PR value.
The oximeter is standalone, reusable, and not reprocessed. The sensor of the
oximeter is built-in.
